ABSTRACT
We studied the nanostructure and physical properties of cellulose nanofiber-multi-walled carbon nanotube (CNF-MWNT) composite films prepared via MWNT aqueous dispersion using 4-O-methyl-α-d-glucuronoxylan as a MWNT dispersion aid. The composite film had high electrical conductivity (1.05S/cm), good mechanical properties (Young's modulus: 10.1GPa, tensile strength: 173.4MPa) and a low coefficient of thermal expansion (7ppm/K). FE-SEM imaging showed that the carbon nanotubes dispersed homogeneously and made reinforcing networks in the matrix of cellulose nanofibers. Improvement in the physical properties of cellulose nanofiber film by adding MWNTs is due to this composite structure.
ABSTRACT
Microsemi LC-767CRP (LC-767, Horiba, Ltd.) is capable of simultaneous measuring of complete blood count (CBC) including 3-part differentials (3-part Diff.) of white blood cells (WBC) and C-reactive protein (CRP) in 4 minutes. Data obtained using LC-767 were intra-assay-reproducible (n = 10, CV = 0.6-4.0% for CBC, 0.6-2.5% for 3-part Diff. and 2.8-7.7% for CRP). They also showed the good linearity, no definite carry-over and the excellent correlations with routine instruments in our institution. Concerning CRP, the minimal detectable concentration revealed < 0.1 mg/dL, and prozone was observed in the sample containing > 30 mg/dL of CRP. LC-767 showed better correlation with a routine instrument in monocyte percentage than LC-667, probably due to modification of the hemolysis solution ratio and diluent temperature. In conclusion, LC-767 provided accurate CBC and CRP results, and showed improvement in CRP linearity and monocyte percentage compared with LC-667. LC-767, which is equipped with a bar-code reader with easy accessibility to electronic medical record, is suitable as the next-generation point of care testing model in the era of information and network-oriented medicine.
